Subject: [PATCH] [NFCi] Fixing build failures on Windows due to std::tie used
 w/o proper include.

From https://reviews.llvm.org/D81236 /
https://github.com/llvm/llvm-project/commit/55fe7b79bb7fab49af3720840224c0720bdb03c6

std::tie is used without including <tuple>. This patch includes <tuple>
so that some downstream Windows bots succesfully build.
